Abstract:

During the twentieth century, particle physics developed into a cornerstone of modern physics, culminating in the Standard Model. Even though this theory has proved to be of extraordinary power, it is still incomplete in several respects. It is our aim in this bachelor thesis to discuss some possible theories beyond the Standard Model, the main focus being on Grand Unified Theories, while also taking a look at attempts of further unication via discrete family symmetry. At the heart of all these theories lies the concept of local gauge invariance, which is introduced as a fundamental principle,

Abstract:

We summarize the standard model and grand unified theories in light of group theoretical properties. We discuss selected classic and modern preon models. Finally, a schematic preon model for all three generations of fundamental fermions in the standard model is constructed. This preon model introduces three spin 0 preons which represent the three generations, as well as two spin 1/2 preons. It incorporates handedness through the fermionic preons.

The subject of this thesis is the improvement of particle tracking through the identification and correction of small systematic errors in particle "hit" locations due to positioning of tracking detectors. These errors call be as large or larger than the statistical spatial resolution of tracking detectors themselves, and therefore must be corrected. The focus is on identification and correction of errors due to rotations and beam axis translations.An algorithm is developed for use with proportional wire chamber and drift chamber detectors in experiment E683 at the Wideband facility of Fermi N

Experiment E683 at Fermi National Accelerator Laboratory (FNAL) in Batavia, Illinois, uses a modular, high-energy sampling calorimeter as the basis of the detector system.

While exiting particles are thought to form what are described as "jets", and several E683 projects involve working with these jets, it has not yet been demonstrated that jets indeed have been detected.The solution proposed here involves demonstrating that E683 data has a statistically si

Abstract:

The proposed neutrino factory, a facility for precision measurements of neutrino oscillations, requires directional neutrino beams to reach the required sensitivities. Among the few sources of such beams is the decay of muons travelling at relativistic speeds, therefore an intense source of muons and subsequent rapid acceleration must be designed so they can reach the required energy before decaying. This thesis considers several stages in this process: pions are produced from a proton beam hitting a target and pion yield optima are determined as a function of target design parameters and the

The ATLAS experiment is used to observe the √s=7 TeV proton-proton collisions produced by the LHC at CERN.

However, in order to produce a search that is sensitive to SUSY it is vital to understand how the physics that has been discovered to date may pr

Abstract:

Doctor of Philosophy<br>Department of Physics<br>Yurii Maravin<br>In this dissertation, you will find a study of di-boson production in pp collision with the Compact Muon Solenoid (CMS) detector at Large Hadron Collider (LHC). A study of Z+gamma process is performed on the data collected by the CMS during 2011 and corresponding to integrated luminosity L= 5 fb[superscript]-1. The study consists of two parts: cross section measurement and setting the limits on anomalous trilinear gauge couplings (aTGC) between a Z boson and a photon. The measured cross-section of Z+gamma agrees within the

Abstract:

Plasmas are used extensively in the manufacturing of microelectronic devices. In typical fabrication facilities, plasmas may be used for etching, deposition, cleaning of a substrate, and chamber cleaning. One of the major challenges to the effective use of plasmas for microelectronics processing is the formation of particles and films from reaction byproducts, which can contaminate both the substrate and the chamber. However, in other communities, the growth of particles and films in plasmas provides opportunities for the production of novel materials, for studies of astrophysical phenomena, a
